Definition of "grinde"

Take of Linet two grains, of Musk three, of Ambergreece four, and the oyl of Bems a pretty quantity; grinde them all upon a Marble stone fit for that purpose; then with a brush or sponge rake them over, and it will sweeten them very well; your Gloves or Jerkins must first be washed in red Rose-water, and when they are almost dry, stretch them forth smooth, and lay on the Perfumes.

The other is to warme the water; and then, when you have put it into a pot, or dish, as much Chocolate as you thinke fit, put in a little of the warme water, and then grinde it well with the molinet; and when it is well ground, put the rest of the warme water to it; and so drinke it with Sugar.
